We only see what interests us, and we have only insight in proportion to our sympathy. - George Henry Lewes

We are not judicious in love; we do not select those whom we ought to love, but those whom we cannot help loving.

A man must be himself convinced if he is to convince others. The prophet must be his own disciple, or he will make none. Enthusiasm is contagious: belief creates belief.

Every one who has seriously investigated a novel question, who has really interrogated Nature with a view to a distinct answer, will bear me out in saying that it requires intense and sustained effort of imagination. The relations of sequence among the phenomena must be seen; they are hidden; they can only be seen mentally; a thousand suggestions rise before the mind, but they are recognised as old suggestions, or as inadequate to reveal what is sought; the experiments by which the problem may be solved have to be imagined; and to imagine a good experiment is as difficult as to invent a good fable, for we must have distinctly present — clear mental vision — the known qualities and relations of all the objects, and must see what will be the effect of introducing some new qualifying agent. If any one thinks this is easy, let him try it: the trial will teach him a lesson respecting the methods of intellectual activity not without its use.
